Engine oils, generally referred to as lubricating oils, are liquids used to reduce friction or prevent contact of parts or surfaces in relative motion, that is, sliding, rolling or rubbing surfaces as in automotive engines. By so doing, they prevent severe wear, rust and corrosion of the engine parts. Other auxiliary functions include; cooling/temperature regulation of the engine parts and prevention of particle deposition on close fitting parts.
During usage, these oils undergo degradation, which turn them black, less viscous and hence ineffective and unfit for further lubrication. Consequently, numerous gallons of these used engine oils are thrown away everyday as “spent” thereby posing serious environmental problems.
The major thrust of Professor Njiribeako’s research is concerned with the resource recovery of these oil wastes including those from industrial machineries. Thus he is involved in the applied research of treatment/regeneration processes of spent engine/industrial oils and development of the prototype pilot plant units for eventual scale –up to industrial plant.
In recent times, Professor Njiribeako and his co-workers have deployed tools and developing new ones for modeling and simulating these waste regeneration processes/systems for optimal control.
